This is just my personal opinion and i am not an expert but a corris wrasse needs a 125 gallon or larger tank and a coral beauty needs a 75 gallon. If you look the fish up, the coral beauty needs plenty of space to hide in rock work. A 29 gal won't provide that.
A corrise wrasse will grow and can reach 6 - 8 inches in an aquarium. A 29 cube is not large enough for a fish that size. It also needs plenty of room to burrow in the sand.
The clowns will be perfectly fine and there are different wrasses you can put with them. Personally, i do not recommend the beauty and corris in that small of a tank. I'm not trying to be a jerk but as reefers, we have a certain degree of responsibility when keeping this livestock and we need to operate reasonably within that.
Bob's advice is in regards to the bioload and keeping the water clean with a high bioload but he doesnt address the fact that this is a far too small of a tank for those fish.
A few gallons is ok but this is a huge difference and both fish will be stressed and pass away.
If you are looking for a certain look of livestock we can recommend some other options. Ultimately, it is your choice but you asked for advice and i am being honest. I personally do not recommend the beauty and corris.
